Question 21

Anthropoda

Answer 21

anthro=joint, pada=foot

Question 22

anthropoda key features

Answer 22

1. exoskeleton (outer, skeletone)
   -composed of chitin and proven
   -strong/waterproof
2. Segmented body plan
   -development of special appendages with joint
   parts
   4.Jointed legs and appendages
   5.high degree of cephalization

Question 23

anthropoda divided into distinct parts

Answer 23

• head: mouth and sense organs
• thorax: walking legs, wings, and part of digestive system, compound eye
• Abdomen: Major internal organs, reproductive organs
• Cephlothorax: head and thorax

Question 24

arthropoda can

Answer 24

transition to land 
-appendages, development of wings
-metamorphosis:
-transition between body forms 
Symbiotic relationships 
-decomposers
-breakdown of dead organisms

Question 25

arthropoda muscular system

Answer 25

1. Muscular-complex system
   a) Muscles occur in bundles & attached to inside of exoskeleton
2. Reduced Coelom; most of the body cavity consisting of hemocoel filled with blood

Question 26

arthropoda circulatory system

Answer 26

• open system
• blood is pumped by a heart (dorsal vessel) into a hemocoel (cavity) blood delivers nutrients + picks up waste directly from organs
• valve in dorsal vessel prevents backflow

Question 27

Excretory System

Answer 27

-Malphigian tubules: drain metabolic waste from body fluids into intestine

Question 28

Respiratory system

Answer 28

• aquatic: use gills
• terrestrial: tracheal system
• branching network of hollow tubes delivers oxygen to organs

Question 29

Nervous system

Answer 29

• two ventral nerve cords
• dorsal brain
• well developed sense organs

Question 30

metamorphosis

Answer 30

• complete 4 stages (egg,larva, pupa, adult)
• gradual: eggs hatch into miniature version of adults
• molting: shedding skeleton when growing and developing

Question 31

Insecta class

Answer 31

• bees/ants: hierarchal order
• pheromones: affect the development and behaviour of colony
• mouthparts specialized for
• piercing and sucking (mosquito)
• biting and chewing (grasshopper)
• siphoning (Butterly)
• sponging (some flies)

Question 32

Arachnida class

Answer 32

• two body regions: abdomen,, cephalothorax
• 8 legs
• major organs in abdomen
• book lungs: gas exchange

Question 33

Crustacea class

Answer 33

• cephalothorax
• two pairs of antennae
• gills used for gas exchange
• 5 or more pairs of legs first pair are pincers

Question 34

Chilopoda class

Answer 34

centipedes

• ventrally flattened
• one pair of legs per segment
• carnivores with poison fangs

Question 35
